Ugh disappointed

Almost 10 months pp still breastfeeding. I’ve had 2 periods (one at 8 months and one just at 9 months about 2 weeks ago). My cycles have been longer than they were before getting pregnant. I was so excited to get my period back so we could start ttc our 2nd babe, butttt I’ve been using LH strips once in the morning when I wake up. They were getting darker last week, but never a true positive. They’re nowhere near positive this week. Just kind of disappointed. I got my hopes up when I got my period back, but it looks like I’m not even ovulating 😢
